Definitions

  • the invention relates to a method for filling a Kraftstoff arrivedan- situation of a motor vehicle with fuel under higher pressure, wherein the fuel storage system has a main filling line to reach a limit pressure fillable main tank and an auxiliary memory.
  • the fuel is hydrogen and reference is made to the prior art in addition to DE 10 2008 060 127 A1 to DE 100 21 681 C2.
  • cryoprint storage Compared with the pure pressure storage has the cryoprint storage has the advantage that larger amounts of hydrogen or generally a storage medium (or fuel) can be stored under lower pressure, which in particular in terms of the weight of the main tank (and thus the weight of a equipped with a motor vehicle) is favorable.
  • the cryoprint storage has the advantage of a significantly lower blow-off quantity resulting from an unavoidable heat input.
  • a motor vehicle equipped with a cryogenic tank as a main tank can not only be refueled with cryogenic hydrogen in a supercritical state, but, if no cryogenic hydrogen is available, gaseous hydrogen can also be filled into the main tank.
  • the pressure build-up in the main tank during a filling process of the same is preferably monitored by means of a suitably placed pressure sensor and then, if with further filling of the main tank the danger of exceeding its limit pressure, another filling by closing a suitable Valve, here called Tankabsperrventil prevented.
  • a suitable Valve here called Tankabsperrventil prevented.
  • an auxiliary storage is connected to the filling upstream of this Tankabsperrventils, so that now supplied by the gas station / supply station fuel enters the auxiliary memory.
  • This auxiliary storage is designed to withstand the maximum pressure level which is usually offered by gas stations for (in this case) gaseous hydrogen.
  • a value of the order of 600 bar to 700 bar is called.
  • auxiliary memory which preferably has a relatively small storage volume, builds then relatively short term, but at least so slowly that the filling system of the gas station in the usual way can react thereto, a pressure corresponding to the maximum pressure offered by the gas station (of 600 - 700 bar).
  • the gas station or electronically controlled by the filling system is then analogous to the filling of other pressure tanks of other motor vehicles, which are designed for the reception of gaseous hydrogen under such a high pressure level, a soft shutdown of the filling initiated.
  • the motor vehicle is equipped with an auxiliary storage device in addition to the main tank, which is preferably a cryogenic pressure tank (cf., for this purpose, the aforementioned DE 10 2008 060 127 A1)
  • the maximum at (here :) hydrogen filling stations can withstand the pressure level offered, however, such an auxiliary memory can be kept relatively small. Since, as explained above, only a small storage volume is needed, such a small auxiliary storage increases the weight of a motor vehicle equipped therewith only to a small extent.
  • such an auxiliary memory can take on additional functions, for example - as is known in principle from the initially mentioned DE 100 21 681 C2 - a partial amount of hydrogen which may also be blown off or removed from the tank in order to avoid an inadmissibly high pressure rise in the tank (general fuel ) for later use or combustion by a consumer caching.
  • a further advantageous additional function of the auxiliary storage may be to enable the operation or further operation of a consumer of the fuel stored substantially in the main tank even during a filling process of this main tank.
  • a so-called supply line via which the load provided in the motor vehicle-preferably a fuel cell or an internal combustion engine-is supplied with fuel from the main tank during a filling process of the main tank.
  • Shut off tanks It is now proposed to connect the auxiliary storage in such a way downstream of a provided in a supply line leading to a consumer check valve, which is closed at a filling of the main tank, in such a way to said supply line, for example. By opening a corresponding valve that the consumer also at closed check valve from the auxiliary memory is operable.
  • a filling line 2 in which a Tankabsperrventil 3 is provided, this main tank 1 at a gas station (supply station) with cryogenic hydrogen in supercritical state or with gaseous hydrogen can be filled under high pressure.
  • a supply line 4 in which a pressure regulating valve 5 is provided, leads to a consumer 6, in particular in the form of a fuel cell.
  • the pressure control valve 5 lowers the prevailing in the main tank 1 hydrogen pressure to a level acceptable for the consumer 6 level.
  • a check valve 7 is provided in the supply line 4, which is closed when the main tank 1 is filled at a gas station.
  • an auxiliary memory 8 for storing fuel or hydrogen is provided which is connected via a feed line 9 to the supply line 4 downstream of the check valve 7, ie on the consumer 6 side facing and upstream of the pressure control valve 5.
  • the auxiliary storage 8 can be connected to the filling line 2 via an auxiliary storage filling line 11 by opening a so-called refueling auxiliary valve 10 provided in the auxiliary storage filling line 11.
  • the tank shut-off valve 3 is closed, after which hydrogen still flows into the filling line 2 and the auxiliary storage filling line 11 and through the open refueling line -Aid auxiliary valve 10 is conveyed to the auxiliary storage 8, until in this provided by the gas station maximum pressure of, for example, 700 bar prevails.
  • valve 12 In the feed line 9 between the auxiliary memory 8 and the supply line 4, a valve 12 is provided which allows the open state that the consumer 6 is supplied with closed check valve 7 with fuel from the auxiliary memory 8 and thus can be operated when another in the supply line 4 here upstream of the pressure control valve 5 and downstream of the junction of the feed line. 9 provided valve 13, whose function will be discussed later, is open.
  • the check valve 7 is kept closed for as long as possible and thus the consumer 6 is supplied from the auxiliary storage 8 until the pressure in the auxiliary storage 8 has dropped to at least the limit pressure of the main tank 1, thus ensuring in that during a subsequent filling operation of the main tank 1 the auxiliary storage 8 can fulfill its essential function described above, namely to prevent a pressure surge reaching the filling station.
  • valve 13 (and of course the valves 10 and 3) are closed and the valves 7 and 12 are opened or are, one can in particular from a heat input into the main - Tank 1 resulting pressure build-up in the main tank 1, through which the limit pressure could be exceeded, are reduced in the auxiliary memory 8 into it without loss of stored fuel by safety from the main tank 1 via the then opened check valve 7 discharged fuel through the Feed line 9 passes into the auxiliary memory 8 and there is temporarily stored until the consumer 6 is supplied from the auxiliary memory 8 with fuel.

Abstract

L'invention concerne un procédé de remplissage d'un système de stockage de carburant d'un véhicule automobile avec du carburant sous haute pression, le système de stockage de carburant présentant un réservoir principal pouvant être rempli par l'intermédiaire d'une conduite de remplissage principale jusqu'à atteindre une pression limite et un réservoir auxiliaire. Dans tous les cas, quand la conduite de remplissage est raccordée à un poste d'alimentation lequel fournit du carburant sous une pression dépassant la valeur limite du réservoir, une soupape d'arrêt prévue dans la conduite de remplissage est fermée à temps avant d'atteindre la pression limite dans le réservoir principal et une soupape auxiliaire est ouverte dans une conduite de remplissage de réservoir auxiliaire dérivée de la conduite de remplissage principal en amont de la soupape d'arrêt et allant jusqu'au réservoir auxiliaire conçu pour recevoir du carburant sous pression plus haute que ladite pression limite. Le réservoir auxiliaire en aval d'une soupape d'arrêt qui est prévue dans une conduite d'alimentation conduisant à un consommateur et qui est fermée lors d'une opération de remplissage du réservoir principal peut être raccordé à ladite conduite d'alimentation de telle manière que le consommateur puisse être alimenté à partir du réservoir auxiliaire lorsque la soupape d'arrêt est fermée.
